Dr. Dr. Evil and Disaster Science Popularization (16) 丨 Is the toad moving a earthquake?

Almost every time the earthquake is permeated everywhere, the claims related to the large toad move and the earthquake -related statement are denyed again and again. Enter the "Toad Moving Earthquake" on the search engine. You can see tens of thousands of records. Without 10%of them are related popular science knowledge questions and answers, most of the others are questions about the relationship between toad moving and earthquakes, experts interpretation, as a certain certain time, as a certain certain time The evidence before the earthquake, the earthquake predictions made after seeing the phenomenon, and various related news, which shows that the degree of attention is high.

So, is the toad moving just an earthquake?

Toad is a collective name for frogs and toads and belongs to amphibious animals. They lay eggs in the water in April and May of the spring every spring. The eggs are incubated into a tadpole to grow and deformation. For example, in May 2010, a large number of toads appearing in Taiping Village, Shiling Town, Chengdu City, Sichuan City, and the rampant situation of "Gathering Tour Street" and "domineering" are the normal migration phenomenon of toads after the toad. In addition, due to its own living habits, habitats, and food shortages, large -scale toad migration phenomena will occur.

It has not been observed so far that there have been direct examples of toad moving and the large earthquake, and there is no practice in the prediction of earthquake predictions as a reference. In individual earthquakes, investigations have found that there are hibernate toads or snakes out of the snake out of the snake out. The phenomenon of the hole.

For example, before the earthquake in Haicheng, Liaoning in 1975, from January 1st to February 4th, the phenomenon of "suicide" in the low temperature environment below 0 ° C in the Haicheng area (most of them were frozen after leaving the hole. ), Analysis believes that this may be due to the increase in the temperature of the local strata due to the crustal movement. The actual survey found that the ground temperature increased at 2 ° C -3 ° C at that time, so this phenomenon was considered to be correlation with the occurrence of earthquakes. In contrast to this, the hibernating snake came out from January 1st to February 10, 1976 to February 10, 1976, which exceeded the situation before the Haicheng earthquake. It is related to the continuous temperature increase. The hibernating snake is out of the high temperature environment of the active temperature line (above 4 ° C), and most of them are active after the hole. Obviously, the hibernating snake in the Linfen area is a natural phenomenon that has nothing to do with the earthquake. This vivid example proves that the abnormal nature of animal habits is not in the earthquake itself.

There is no scientific basis that toads have the ability to aware of earthquake activities in advance.

In fact, many toads have been "reported" over the years, and have not occurred after being "reported". Similarly, whether in Japan, the west coast of the United States, the Taiwan, Taiwan, and Southwest provinces, toads have not moved frequently because of the arrival of the great earthquake. Therefore, whether it is a snake or toad, the big move does not indicate a earthquake.
